Extension: Campus after school: After class, students begin to pack their schoolbags and line up like active birds. Some of them were flying freely on the playground like wild birds. After a while, all the students in the campus disappeared. After school, you can even hear the sound of a needle falling to the ground on campus. There is no laughter on the playground, and there is no sound of students reading in the classroom, followed by a faint sunset.
